Title: Method and device for measuring plasma density distribution
Inventor: SAKAI TAKAYUKI
IPC: G01N21/62
Filed: 1991-09-27
Abstract: PURPOSE:To measure three-dimensional plasma density distribution by calculating the light intensity of plasma at predetermined points within the same plane within the plasma, the light intensity being measured along passages extending in all angular directions including those points. CONSTITUTION:While plasma is moved in the direction perpendicular to the rotating face of the rotary magnet 14 of a plasma processing device 10 and in the direction of rotation, the intensity of the plasma light from the light transmitting window 12 of a plasma generation chamber 11 is converted into beams of parallel rays by the collimator 21 of a plasma density distribution measuring apparatus 20. Next, the plasma light obtained via the collimator 21 is converted into an electric signal by a photoelectric converter 23 and the intensity is measured by a light intensity measuring instrument 24 and the density distribution of the plasma within the plasma generation chamber 11 is calculated by a computing element. Thereby projection data can be obtained through simple constitution and the use of the princiles of CT enables three- dimensional plasma density distribution to be measured at desired accuracy.

Title: Method of heating ceramic heating unit which is heat source in water heater
Inventor: NAKAGAWA SUSUMU
IPC: F24H1/18
Filed: 1983-12-30
Abstract: PURPOSE:To quicken the rise-up of an exothermic reaction by installing an igniting device at the upper opening part of a ceramic heating element, and igniting an organic volatile agent which flows through the ceramic heating element at the outlet of a through hole. CONSTITUTION:The igniting device 4 is installed in the proximity of the upper opening of the ceramic heating element 1. The organic volatile agent 3 which flows through the heating element 1 is ignited at the outlet of the through hole 2 by the igniting operation of the igniting device 4. As a result, the heating element 1 itself becomes a combustion body to burn and a flame 5 rises up from the outlet of the through hole 2 and the surface of ceramics and displays a flaming state as if it were a briquette. Hence, the rise-up of the exothermic reaction is fast.
